An article published in the journal “The Anatomical Record” reports a study of the anatomy of Tyrannosaurus rex’s skull which offers an explanation of how it could have bite so powerful that it could crush of its prey’s bones without breaking its own bones. A team of researchers led by Ian Cost of Albright College examined the characteristics of the T. Rex skull also using computer simulations concluding that it was as stiff as those of modern hyenas and crocodiles and not as flexible as those of snakes and birds.
